KANSAS AIRPORT WORKER ARRESTED IN CAR BOMB PLOT: WICHITA, Kan. (AP) — A Kansas man who prosecutors say sympathized with violent terrorists was arrested Friday as part of an FBI sting after he drove a vehicle loaded with what he thought were explosives to a Wichita airport.

Loewen, a 58-year-old avionics technician who worked at the airport for Hawker Beechcraft, was arrested before dawn as he tried to drive onto the tarmac. The materials in the car were inert, and no one at the airport was in any immediate danger, authorities said.

Loewen, who lives in Wichita, had been under investigation for about six months after making online statements about wanting to commit "violent jihad" against the United States, U.S. Attorney Barry Grissom said. An undercover FBI agent befriended Loewen, striking up conversations about terrorism and Loewen's admiration for those who plotted against American interests.

GUNMAN, 18, WOUNDS CLASSMATE IN COLORADO SCHOOL: CENTENNIAL, Colo. (AP) — A teenager who may have had a grudge against a teacher opened fire Friday with a shotgun at a suburban Denver high school, wounding a fellow student before killing himself.

Quick-thinking students at Arapahoe High School alerted the targeted teacher, who quickly left the building. The scene unfolded on the eve of the Newtown massacre anniversary, a somber reminder of the ever-present potential for violence in the nation's schools.

The wounded student, a 15-year-old girl, underwent surgery and was in critical condition. Authorities originally said a second student was wounded, but Arapahoe County Sheriff Grayson Robinson said Friday night that the other girl taken to a hospital was covered in blood from the first student and wasn't injured.

Robinson identified the shooter as Karl Halverson Pierson, 18. The sheriff did not elaborate on any possible motive except to say Pierson had a "confrontation or disagreement" with the teacher. He didn't know if the injured girl was intentionally shot.
